Systems and methods for sampling

A system comprising:

• a capillary having a first end connected to a sampling device and a second end, wherein the sampling device is configured to separate a sample with a separation solution and deliver the sample and the separation solution to the second end, wherein the second end is coupled to a capillary ground contact;
• a transport liquid supply system in fluidic communication with a transport liquid supply conduit that provides a transport liquid from a transport liquid source through the transport liquid supply conduit, wherein the transport liquid provided from the transport liquid supply conduit comprises a receiving volume defined at least in part by a meniscus, and wherein the second end of the capillary is in fluidic communication with the receiving volume;
• a liquid exhaust system in fluidic communication with a removal conduit that removes liquid from the receiving volume;
• an electrical conductor for connecting the transport liquid supply conduit to the removal conduit;
• a first electrical contact connected to the transport liquid supply conduit;
• and
• an analysis system in fluidic communication with the removal conduit.
